280 / 300 tire motorcycle swingarm kits are bolt on replacements for the stock 2008-11 Harley Softail swing arms and they enable you to mount a 280 or 300 tire on your stock Twin Cam Softail without doing any modifications to the frame.

These 280 / 300 tire motorcycle swingarm kits can be installed only in conjunction with a 20mm secondary belt and can fit up to 10.5” wide rims. Thanks to this innovative wide swingarm you will be able to mount a super-wide rear tire, without any modifications to your stock frame, still keeping front and rear wheels properly lined up for safe riding and great handling.
